A cutting tool for producing decorative cake components is provided. The cutting tool includes a roller including a plurality of cutters located on a radial outer surface thereof and two end portions located on opposite ends of the roller.

The invention provides a flattening method for flattening the edges of a swatch of flexible material from which pieces are to be cut out. The method comprises: establishing a digital representation of at least a portion of an outline (H.sub.C) of the swatch of flexible material (H); establishing a specific flattening direction (D.sub.i, D.sub.j) and distance (V.sub.i, V.sub.j) for each of the points (P.sub.i, P.sub.j) of the scanned portion of the outline of the swatch; and for each selected point of the scanned portion of the outline of the swatch, using a presser foot of a cutter tool, to flatten the edges of the swatch along the specific flattening direction and distance established for said point, and along a flattening direction going from within the swatch towards its edges.

A method of manufacturing a metal cannula is disclosed. The method includes the step of providing a metal cannula having a longitudinal axis and defining a fluid channel. Next, the metal cannula is pressed to substantially close the fluid channel and define a first segment and a second segment. In a next step, the metal cannula is cut to separate the first segment from the second segment of the metal cannula. Each of the first and second segments have a pressed edge. The pressed edge substantially seals the fluid channel and has two pressed corners. Afterwards, each of the pressed corners are cut from the pressed edge of the first segment to define a pair of side openings and a distal blunt edge on the first segment. The side openings are in fluid communication with the fluid channel.
